Consider the paraboloid f(x, y) = 16 - x2/4 - y2/16 and the point P on the given level curve of f. Compute the slope of the line tangent to the level curve at P and verify that the tangent line is orthogonal to the gradient at that point. f(x, y) = 0; P(0, 16)

answer: b

step-by-step explanation:

the answer is 8.64

step-by-step explanation:

wait this depends wether emily and zach how they are thinking.

yes they are the same.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
